Description

The invention relates to a device for displaying digital photos. More particularly, the invention relates to a device for displaying digital photos with a positioned in a housing, while a housing of the device includes a front part, located around the display and having side edges and a back part closing the device from the back, and also having side edges.
Devices for displaying digital photos are known. These are electronic devices equipped with a display - typically a liquid crystal with a diagonal from a few to several inches - arranged in the housing. The devices equipped with a small display are referred to colloquially as "frames for displaying photos." The device is controlled by a microprocessor programmed accordingly. The device has a stand, which allows for setting it in a position close to the vertical one, e.g. on the nightstand. This is the normal operating position of the device - in this position the photos displayed on the display are clearly visible to the user. A stand can be a separate element that can be integrated with the housing or may be a suitably shaped part of the housing. The devices typically have a substantially rectangular shape, with sides of different lengths. Therefore- according to the orientation of the displayed images the user placing the device in said substantially vertical position as the position of the operation may give the device a portrait type orientation (English portrait) - when the shorter edge of the device is its lower edge or landscape type orientation (English landscape) - when the longer edge of the device is its lower edge. Built-in batteries or - more often - an external power supply, with which the device is connected to the wall outlet are used to power the device. In turn, the built-in batteries also require regular charging, which is typically done using an external power supply. The source of the displayed images may be internal memory, built-in device, or various types of storage media, e.g. a memory card or USB memory stick that can be connected to the device via appropriate connectors that the device has. One or more buttons (or other controls - sliders, knobs) are used to control the device. Both the socket for the power connection and the external memory slot (USB, cards), and the said control buttons are arranged in the housing of the device. There are devices equipped with wireless communication modules (e.g. WiFi), so that the photos can be transferred to the device wirelessly.
The term "digital photos" as used herein is widely understood - as any visual information fit for display. This can be any image files formats supported by the device, in particular popular formats jpg, gif, bmp. The displayed images can contain inscriptions. For example, along with an image, a message from the author's photo may be displayed and/or name of the author.
An exemplary construction of the device was disclosed in the patent application No. US 2009/0219245 A1 . The device has a display located at the front, whereas at the back, i.e. on the back wall of the device's housing, it has controls (buttons) dedicated and available for the user, power supply, USB and memory card ports and a support. The said buttons and sockets are not hidden, in particular in another part of the device's housing. The said support is a separate part, which only function is to stabilize the vertical position of the device. The support is not a part of the device's power supply. In turn, the power plug inserted in the designed socket does not support the device in any way.
Another device is disclosed in Korean document KR 10-2011-0095490 . In this case, the control elements (buttons) are located at the front of the device, around the display.
In turn, US industrial design No. US D545,782 S discloses a device, wherein the housing has an integral bent part, which is a stand that allows to set the device in a substantially vertical position. The controls are located on the front of the housing, below the display, at the bottom, i.e., near the place where the device housing is bent to form a support. In turn, the ports (USB, memory card, power supply) are disposed on the back of the device's housing and are not covered with any other part of the housing.
Tablets are also known, which can serve as a device for displaying digital photos, if only the right program is started. Tablets can communicate wirelessly (e.g. using WiFi, GSM, UMTS, LTE, etc.) and this way download photos to be displayed. Typically, tablets are not designed to set the vertical position. To do this - one needs to use the docking station or a special stand. Such support is not an AC charger plug for the tablet. Tablets usually have one socket for connecting to an external power source. Tablets do not have a sectional housing, whose parts would be hinged and overlap so as to hide the controls external memory connectors, located in the second part of the housing, under one part of the housing.
The need of supplying electricity to the device or systematic device battery charging entails using the AC adapter. Regardless of the need to set the device in a substantially vertical position (that is, in the typical position of operation - so that the displayed images were visible) requires the use of additional elements: stands, tripods, docking stations, etc. This complicates the overall structure of the device, which in itself is simple and makes the device more difficult to use. Also, constant availability and the multiplicity of controls, buttons, sliders and connectors - even if they are located on the back of the device - can cause the users (e.g. the elderly people) to have the wrong impression that they are dealing with the complex device, difficult to use, etc.
It is therefore desirable to simplify the construction of the device, in particular by reducing the number of elements (parts, components) required for normal use of the device.
Furthermore, it is desirable to place the controls, buttons, sliders and connectors so that they are readily available at the time when they are needed by the user and could be easily hidden/masked when they are not needed.
Therefore, the object of the present invention is to provide a device for displaying digital photos fulfilling the above mentioned requirements.
According to the invention, a device for displaying generally rectangular digital photos, having a front display for displaying digital photos, positioned in the housing, wherein the housing of the device comprising a front part located around a display and having side edges, that is, walls substantially perpendicular to the plane of the display and a back part, closing the device from the back, and also having side edges is substantially perpendicular to the wall plane of the display, characterized in that one of the side edges of the back part of the housing has ports and/or controls, and a back part of the housing is hinged inside the front part of the housing and can move relative thereto in a reversible manner between a first part in which the said ports and/or controls are hidden under one of the side edges of the front part of the housing and a second position in which said ports and/or controls are exposed and accessible to the user.
Preferably, the hinged connection of the front and back part of the housing of the device comprises hinges arranged in the middle of two opposite sides of the device, preferably the shorter sides of the device.
Preferably, the device according to the invention has a locking latch to allow blocking the back part of the housing relative to the front part of the housing in the said first position or the said second position.

The following indications were used in the drawings: 1 - device, 2 - power supply, 3 - ports (including: 3a - miniUSB port, 3b - first type memory card port e.g. MemoryStick, 3c -second type memory card port e.g. microSD) and controls, 4 - display, 5 - power supply plug-in for connecting to a power source (first power supply plug-in), 6 - power supply plug-in for placing in the electrical socket of the device (second power supply plug-in); 7 - second electrical socket, 8 -first electrical socket, 9 - back part of the housing, 10 - first edge of the housing, 11 - front part of the housing, 12 - second edge of the housing, 13 - side edge of the front side of the housing (substantially perpendicular to the plane of the display).
In the presented preferred embodiment, the device 1 for displaying digital photos has a substantially rectangular shape, with edges of different lengths. The device 1 has a display 4 arranged in the housing (9-13) at the front. The housing of the device 1 comprises a front part 11 located around the display 4 and having side edges 13, that is the walls substantially perpendicular to the plane of the display 4 and the back part 9 closing the device 1 from the back and also having side edges, that is the walls substantially perpendicular to the plane of the display 4. In the accompanying photos the front part of the housing 11 is white, and the back part 9 - black (Fig. 1, 5, 6).
The back part 9 of the device's 1 housing there are two identical electrical sockets 7, 8 for connecting the power supply 2. First of these sockets 8 is located near the edge 10 of the housing, in the middle of one of the longer sides of the device 1. Second of these sockets 7 is located near the edge 12 of the housing, in the middle of one of the shorter sides of the device 1. The shorter and the longer side of the device 1 are perpendicular to each other (Fig. 1, 2, 4, 5, 6).
Moreover, one of the side edges of the back part 9 of the housing has ports 3a, 3b, 3c: mini USB 3a and two memory card ports 3b, 3c of various type. In general, they can be any ports and/or controls 3a, 3b, 3c. The back part 9 of the housing is hinged inside the front part 11 of the housing and can move relative thereto in a reversible manner between a first position in which the said ports and/or controls 3a, 3b, 3c are hidden under one of the side edges 13 of the front part 11 of the housing, and a second position in which the said ports and/or controls 3a, 3b, 3c are exposed and accessible to the user (Fig. 2, 4, 7, 8, 9).
The hinged connection of the front 11 and the back part 9 of the housing of the device 1 is accomplished by means of hinges arranged in the middle of two opposite shorter sides of the device 1. Alternatively, longer sides can be chosen. The device 1 also has a locking latch to allow blocking the back part 9 of the housing relative to the front part 11 of the housing in said first position or said second position, according to the user's needs.
Presented device can be supplemented with a power supply 2 for energizing the device, having a first plug-in 5 used to connect it to a power source (e.g. home electrical network) and a second plug-in 6 electrically connected thereto with a wire for placing in the electrical socket 7, 8 of a device 1 for displaying digital photos. In the presented embodiment, the first plug-in 5 of the power supply 2 is a standard plug-in used to connect to a common electrical network, and the housing of the first plug-in 5 of the power supply 2 has a transformer - but it is not necessary (Fig. 3).
It is important, however, that the shape and dimensions of the second power supply 2 plug-in 6 and placement of the electrical sockets 7, 8 for connecting the power supply 2 in the back part 9 of the housing of the device 1 can be intentionally selected. Namely, each of the two electrical sockets 7, 8 is arranged in the back part 9 of the housing of the device 1, near its edge, and the second power supply plug-in 6 of the power supply 2 has a shape and dimensions such that when it is placed in any of said electrical sockets 7, 8 of the device 1 is a stand holding the device 1 in a substantially vertical position (that is, in the normal operating position of the device 1). Thus in the present invention, the functions of a stand and bringing power to the device are integrated (Fig. 1, 5).
In the presented embodiment, connecting the second plug-in 6 of the power supply 2 to the first socket 8 provided on the longer edge 10 of the device, allows to maintain the device 1 in a substantially vertical position, wherein the said first edge 10 of the housing becomes a lower edge of the device 1, and thus the device 1 gains the landscape-type orientation - Fig. 6. Similarly, connecting the second plug-in 6 of the power supply 2 to the second socket 7 provided on the shorter edge 12 of the device, allows to maintain the device 1 in a substantially vertical position, wherein the said second edge 12 of the housing becomes a lower edge of the device 1, and thus the device 1 gains the portrait-type orientation - Fig. 1, 4. It is obvious that integrating the functions of a stand and bringing power to the device is related to the location of the socket 7, 8 and shaping of the second plug-in 6 of the power supply 2 and can be implemented also in the device of one socket, three sockets and the like. On the other hand, performing two electrical sockets 7, 8 of the device 1 on the longer and the shorter edge of the device 1 allows for convenient change of the device's 1 orientation. For the realisation of the present invention it is not necessary for the device's electrical socket or sockets to be in the middle of the edge of the housing. The socket may be located elsewhere in the edge, and in particular even at its rim. The socket located in the middle of the edge provides the most stable support of the device. Finally, for the realisation of the present invention, the device doesn't need to have a rectangular shape - a device with a different shape - triangular, polygonal, oval, etc., can be supported in this way too.
Regarding shaping of the second plug-in 6 of the power supply 2 - an exemplary shape of such a plug-in 6 is clearly visible in Fig. 3 and 6. The plug-in 6 has a substantially square cross-section, with a cross-sectional area increasing in the direction of the electrical contact extending from the socket 6. The shape may, however, be different, as long as the length of the plug-in 6 provides a stable support of the device 1. From this point of view, a preferred shape is flattened, wherein the contact surface of the object, on which device 1 stands (table, cabinet) is as large as possible. Plug-in 6 may include additional ribbing, grooves, etc. to facilitate removing it from the socket of the device.
The display of the device may be a touch screen display. In this case, the control of the device can be carried out using a dedicated interface (application) displayed on the display.
The remainder the device 1 uses well-known electronic components, particularly memory and a microprocessor programmed accordingly. Moreover, the device 1 can be equipped with wireless communication modules (e.g. WiFi GSM, UMTS, LTE), so that the photos can be transferred to the device wirelessly.
As mentioned initially, devices equipped with a small screen - typically with a diagonal of a few to several inches - are commonly called "frames to display photos." However, the present invention is not limited to devices with a single small display. The device according to the invention may essentially have any display size. May have two or more displays. In the end - an area on which the image ("display") is presented may consist of a plurality of displays, respectively arranged side by side.
The present invention allows to significantly simplify the construction of the device, in particular by reducing the number of elements (parts, components) required for normal use of the device. Furthermore, it provides such an arrangement of the controls, buttons, sliders and ports to be readily available at the time when they are needed by the user and could be easily hidden/masked when they are not needed.
